Indiana, have invented new and useful Im-- provements in Cultivators, of whichthe fol lowing is a s ifi ti p Myinvention relates to certain new and useful improvements in cultivators; and it consists in mechan'ismof; peculiar construction whorebythe parallelj relatio'n' of the plows is. maintained, all hereinafter more'particularly I described, and pointed out in the claimsl The objects of iny invention are, first, to provide means whereby either of the plows of the cultivator may' bemove'd in a horizontal plane, either inwardly or outwardlyand 'in '7 dependently of eachother and whereby the supporting mechanism of said plows will antomatically move toadjust itself to the various positions inlwhich thefplowsfmay be set to maintain the latter insuch adjusted position 5 to provide means whereby said plows when moved into a'nypositio'n inwardly or outwardly nearer toor from each other will automaticallymoveto be infparallel relation to eachother and whereby thefsaid parallel relationwill be maintained to provide means wherebythe draft 'o'r pull ofjjthe team will be directly applied toj 'the "plows"that is, the line of direction of the pull willpass from the neck-gear of said team onhorses' directly through the hitching 'm'eans' 'to the points of the pairs of'gang-plows, and thereby relieve the neck-yoke of all downwardpr essure. I attain theseobjectsby-means of the improved construction ofcultivator illustrated in the accompanying difawings in w'hich. similar,

Fig. 3 is an enlarged broken inverted plan- View of thelsamedookingin'the direction of the arrow ct, Fi 1. Fig. 4 is adenla'rged detail elevational view of the radius-bars or parallel-link mechanism; Fig. 5 is a plan view 'of the same, and Fig. 6 is an enlarged detail sectional view of the swivel-piece to which the plows are connected. t

The main frame of the cultivator is composed of the rear; parallel bars 1 and 2,;be-

tween which thseparating-blocksB and A; are'- securely bolted, and the diagonally-ex tending side bars:5 and 6, which latter are secured at'the rear ends to the lugs 7 and 8, form'edintegr'al on the top sides of said separating-blocks 3 and 4. Thetongue or shaft '9 is firmly secured to and between the forwardportions or arms 1O and 11 ofsaid diagonally-extending side bars-5 and 6 by suitable bolts 12. The axles'13; whichare preferably circular in c'ross-secti'on,are cranked to extend below the plane of the rear frame-bars'or'parallel bars 1 and 2 suificientl'y far to raise the machine the-proper distancefrom the ground when the su pporting wheels l lare mounted on thelower'cranlged ends thereof,- and saidaxles have their inwardly-extending upper cranked endsloosely fitted in the bores' of the bosses 15, t "which latter are formed integral on the lower endsof theseparating-blocks"3 and 4:, and

the said axles can be adjusted either for-i wardly or rearwardl'y an extent to properly balance the m'achineOr to bringt'hecenter of gravity of themachine directly overthe center of the axles. The sidebars l6'aii df17 are bent to extend'inwardly jtoward the diagonally-extending' bars 5 and -6,1 to which latter they are securely bolted, andthe said bars 16 and 17'are'alsobentat their rear ends to lap 'overa portion of the ends offthe bar 1 and to which they are bolted. yThe axle-braces l8 extend-from the lower cranked ends. of the axlesflf-l td the brace-carrier 19, to which their'upperfends arebblted, and the said brace-bars 18 are provided for the purpose of retaining 1the'axlesf13 in any desired position, either forwardlybrb ackwardly of the center of gravity of the 'maiifffrajme. 'The'com'pens'ating radius-bars, each'ofw'hich is alike, are composed ofthe upper and 'lower arm members'20 and 21,'to the rear or hinged ends of which are permanently secured the upper and lower hinge-hubs 22 and 23 'v e'rtically one above the other, and whichlatter are hinged on the support-ing brackets 24 by the hinge-pins 25. The supporting or hinge brackets 24 are secured to the diagonallyextending frame-bars 5 and 6, at or near the rear ends thereof and in position thereon to permit the necessary horizontal swing ofsaid radius or compensating bars 20 and 21. -The upper and lower hubs 26 and 27 are permanently secured in vertical alinement on the forward or free ends of the upper and lower arm members and 21 of the radius or compensating bars, and the said forward hubs 26 and 27 and rear or hinged hubs 22 and 23 are each connected by the yokes 28 and 29, formed integral therewith, and-thus the various members composing said radius-bars are permanently and securely connected together to form a strong and rigid structure. The hubs 26 and 27 are each drilled to receive the vertically-extending depending swivel-pieces 30,

which latter are adapted to turn therein. Retaining-collars 31 are situated between the hubs 26 and 27 and secured to the swivel-pieces to retain the same in position. The top ends of the swivel-pieces 30 project upwardly above the hubs 26, and the swinging arms 32 are keyed or otherwise secured in position thereon. Aconnecting-link 33, which is of a length equal to the length of said radius-bars,exte nds from each of the arms 32 to the retainingbrackets 34, wherein they are pivoted, and the said brackets 34 are secured permanently in such position on the diagonally-extending 4 frame-bars 5 and 6 that the fixed centers of said links will be in alinement with the centers of the radius-bars, and thus when the radius or compensating levers or bars are swung to either the right or left, as indicated by the arrows, the arms 32 will be moved to turn the swivel-pieces 30, as indicated by the arrows d.

The bottom or depending ends 35 of the swivel-pieces 30 are of a disk form, and to each of said disks, against the parallel faces thereof, are bolted the swivel-disks 36, which latter have their swivel-hubs 37 projecting from and formed integral on their bearingfaces, and the said hubs are adapted to fit in the central bores of said disks to turn freely therein. Retaining-lips 33 are formed on the outer faces of said disks 36, between which the forward or draft ends of each of the outer pairs of bars 39 are fitted and secured to said swivel devices or disks 36 by the bolts 40, which latter pass through each of said disks 36, thedepending disk ends 35 of said swivelpieces 30, and the bars 39 to bind them together to form a swivel-joint to permit each of the gang-plows 63 to swing upwardly or downwardly or to riseand fall, and thus the gang-plows 63 are connected at their forward ends to swing in either a horizontal or vertical plane.

Integral on the lower hinge members 23 of the radius-bars are formed the seatings 41, to which are securely bolted the quarter-turned connecting-pieces 42. To these pieces are connected the links 43, which are connected at their forward ends to the free ends of the balancing-lever 44. The balancing-lever 44 is pivoted at its central portion to the draftbar 45, at or near the rear end thereof, by the bolt 46. The draft-bar 45 is situated beneath the tongue 9, at the rear end thereof, and is guided between the guide-lips 47, formed integral on the pieces 48, which latter are permanently secured to said tongue 9, and said draft-bar 45 is adapted to slide longitudinally between said guide-lips 47 a limited amount, said draft-bar 45 being held in position between said lips by the retaining-bolts 49. An equalizing-lever 50 is pivoted at its central portion to the draft-bar 45, at a point intermediate the ends thereof, by a bolt 51, and the free ends of said equalizing-lever 50 are connected to the hitching-bar 52, at points between the pivotal center and the free ends thereof, by the links 53. The hitching-bar 52 is composed of the upper member, which extends over the tongue 9, and thelower mem-.

ber, which extends under said tongue 9, and said lower and upper members are securely riveted together, and a pivot-bolt 53 passes through said tongue 9 and the upper and lower members of the hitching-bar 52 to pivotally secure the latter to said tongue 9. The hitching-bar 52 is bent to extend outwardly and downwardly from its central portion toward the downwardly-depending ends 54 thereof, to which latter ends the draft-gear of the horses is attached and in such a manner that a line drawn from the points of the leading plows of the gang-plows through the free depending ends 54 of the hitching-bar 52 will pass through the point at which the draftgear is connected to the neck-yokes of the horses or team. The seat 55 is provided with the forwardly-extending supporting-arms 56, i

the forward ends of which are bent or looped, as shown in Figs. 1 and 2, to encircle the yielding depending arms 57, which latter are secured at their forward ends to the inner side bars 58. The lifting-levers 59, which may be of any suitable form of construction, are pivoted on their supporting-standards 60,and which latter are securely bolted to the inner bars 58. A yielding connecting means extends from each of the lower lever-arms 61 to thefront end of the central bars 62 of the gang-plows 63in the usual way peculiar to this type of plow, and the said means may consist of a coil-spring connected at its top and bottom ends by suitable links to each of said lever-arms 61 and to the gang-plows 63, as previously described.

The manner of practicing my invention 1 will now proceed to describe. The team or other traction means is first hitched to the machine, so that the pull of the tugs or draft portion of the harness thereof is applied directly to the ends of the hitching-bar 52 when the team is moving forwardly. The draft or pull is then directly transmitted to the draftbar 45, through the equalizing-bar 44, which terbalance the forces of resistance exerted by each of the gangs of plows 63 at the free for- These forces as applied to the arms 42 counward orswinging ends of said radius-bars, to

erator seated on the seat 55 places his feet in' the guiding-stirrups 65, connectedto each of which ends said plows are pivotally connected by the swivel-pieces toswing in a horie.

The opthe gang-plows, at the rear ends thereof, and by means of saidstirrups 65' moves either or both of the gang-plows into any position either inwardly or outwardly or nearer to or farther from each other. The compensating or radius bars immediately swing into position si-- m ultaneousl y as the operator moves theplows into any new or adjusted position to retain said plows in said adjusted position either inwardly or outwardly, and thus maintain them in parallel relation to each other and with the line of direction of the draft; The inwardlyextending arms 32, connected by the links 33 formed and with little exertion on the partofthe operator, in which adj ustedpositions'said radius-bars remain until moved into a 'new' to a fixed point, are moved positively to turn the swivel-pieces 30, and thereby move. the plows connected to the latter to-assume parallel positions relatively to each other'when said radius-bars are swung into any new p0 The latter paralleling mechanism sition. may be dispensed withwhen it is desired-that the plows 63be permitted to freelyswing in their horizontal planes on their swivel ends by virtue of the draftaalone and the resistance in opening the ground'when the arms or 4 radius levers or bars are swung into new positions, or vice versa; j Whenit is? desired to move the plows 63 into any new position by moving the radius-bars, the operator grasps the handles 66,-by meansof which either orboth the radius-bars swing either inwardlyor outwardly into new positions, which move ment or working of said levels is readily perpositionby'the operator, and the plows 63,
